SUPPORT FOR DRIER-APRONS.

Specification of Letters Patent.

Patented Dec. 2'7, 1921.

Application filed December 13, 1920. Serial No. 430,116.

1 '0 all" whom, it may concern..-

lle it known that I, ALLAN C. SARGENT, a citizen of the United Eltates, residing at Westford in the county of Middlesex and State oi Massachusetts, have invented new and useful Supports for Drier-Aprons, of which the following is a specification.

This invention relates to an improved form of carrying supports for use under traveling endless aprons on drying machines.

The principal object of the invention is to provide improved means whereby the several supporting members that carry the apron will. not have to be carefully drilled because their alinenient will not depend upon the drilling. in this way a great deal of labor is saved in manufacture and particularly in assembling. e

Other objects oi. the invention are to simplify the means for carrying the aprons and to arrange them so that in case of accidental loosening of the rods that go through the drier the supports will not get out of position unless the condition is so bad as to throw them all out.

Reference is to be had to the accompanying drawings, in which- Figure 1 is a transverse sectional view of a drier showing a series of these supports mounted in accordance with this invention;

l ig. 2 is a similar view of one side oi the device on enlarged scale showing the supporting casting in section, and

Fig. 3 is a longitudinal sectional view on the line 3--3 of Fi g. 2.

The invention is shown as applied to a drier 10 having an endless conveyor apron 11 moving tl'iereii'i for conducting the material to be drier. The edges of the apron rest on a series of longitudinal angle irons 12 secured to the sides of the drier and above these there are inclined walls 13 for a welllmown purpose.

The part oi the conveyer which supports the material to be dried is itself supported. at intervals across the drier by a series of Longitudinal angle irons 15. Each of th pipe 18 extending almost all the way across the drier with its ends fitting intd a pair of" cupped collars l9 engaging the inner sides oil? the drier casing. When the nuts 17 itened up this whole structure is fixed in portion and no part of it can get out of position independently of the rest of it.

For the direct support of the angles 15 I provide a corresponding number 01' castings 20 on each of the pipes 18. Each casting is provided with a cylindrical perforation for receiving the pipe and a set-screw 21 is employed for securing it fixedly thereto in any desired position lengthwise of the pipe.

I th of these castings 20 is provided with a slit-.22 extending vertically down from the top and. located in a projection 23 extending upwardly from the middle of the casting. These slits therefore are longitudinal with res ect to the drier and each receives the lower flange of one of the angles 15, this l'lange being vertical. These flanges areheld in pos tion by set screws or the like 24. It will be understood that a plurality of these castings 20 located. on a corresponding number of pipes 18 will support each of the angle irons 7.5 so as to hold them in horizontal position, so that their upper surfaces constitute supporting tables or tracks over which the conveyor ll slides.

'lllhesc anglcsare easily alined and can be used direct from stock without any preliminary s eiacing or drilling as no holes have to he put through them. This in itself makes them easy to assemble and reduces the cost of that operation very materially. On account of the several angles being in contact with the bottom oi the conveyor and their being supported at intervals, there is not much teiulency for them to turn on the rod lo and consequently the set screws 21 ar suliicient to hold them in position.

.illthough I have illustrated and described only a single term of the invention I am aware of the fact that modifications can be the other in one piece, a plurality of supports each having a passage therethrough Iitting and fixed to the pipe and provided the drier inside from on side to'the other in one piece, cupped collars on the rod at both ends for receiving the ends of the pipe, a plurality of cast supports each having a passage therethrough fitting and fixed to the pipe and provided with an upwardly extending projection slit transversely at th .top, and angle plates each having a vertical oftheplates to turn out of place about the rod will be resisted by the others.

' 3. In a conveyer apron support for a drier, the combination of a supporting pipe, a casting fixed thereto and having an upward projection slit vertically part way down from the top, and an angle iron having a vertical flange secured in said slit and a horizontalflangoabove for supporting the couveyer apron.

In testimony whereof I have hereunto al fixed my signature.

ALLAN C. .SARGENT.
